System and method for efficient database transactions

ABSTRACT

A system and method for processing database transactions wherein the need for a DBMS server to convert data provided by the client from a text format to the raw storage format of the database is eliminated, thereby increasing the efficiency of the DBMS.

BACKGROUND

A database is an organized collection of data that can be used by client devices for many different purposes. The usage of a database is typically managed by a database management system (DBMS) having servers (DBMS servers) that maintain the database and manage interactions with and transactions requested by client devices. Basically, software on the client device interacts with software on the DBMS server through a communications network to initiate and execute a transaction. The transactions are guided by a set of routines, protocols and toots defined by an application-programming interface (API).

In a traditional DBMS, when a client device wants to access a database, it will formulate a query or request for information access to the database. In response to the request, at least one statement will be generated that, when executed by the DBMS server, satisfy the request. Examples of statements include INSERT, COPY, and UPDATE, which insert data into the database, copy data within the database, and update data within the database, respectively. In the event that the client device has data (client data) that it wants to insert into the database or update data within the database, once the statement is generated, the client device can call an API and provide the client data to the DBMS server that will execute the statement.

The client data is typically communicated from the client device to the DBMS server in any one of a number of text formats including, for example, JavaScript Object Notation (JSON) and Extensible Markup Language (XML). However, data is not typically stored in the database in a text format. The format in which data is stored in a database, referred to herein as the raw storage format, is typically proprietary and thus different for different databases. As a result, when the DBMS server receives the client data, it typically needs to convert the data from a text format to the raw storage format of the database.

To illustrate, a client device that wants to update a record in a relational database may form a request that includes a statement that looks like INSERT INTO TABLEA (col1=‘A’, Colb=10). In this statement, the client data (col1=‘A’, Colb=10) is in a text format. However, the raw storage format of the database could look something like ‘00101 A02002010.’ As a result, in order to execute the INSERT statement, the DBMS server needs to convert the text-based data (provided by the client device) to the appropriate raw storage format of the database.

It can therefore be understood that in a traditional DBMS, the DBMS servers need to essentially perform such conversions (text format to raw storage format) for each database request from every client device using the database. As the number of client devices accessing the database and the number of database transactions gets large, the conversions can require a substantial amount of server computing power and, as a result, DBMS performance can suffer.

As described in the background section, a client device can interact with a DBMS server to access a database maintained by the DBMS server. The DBMS server basically exposes application-programming interfaces (APIs) that the client device can call to access the database. A query or request to access the database is formulated and planned, and a statement is executed to effectuate the request.

When a client device wants to add or update data within the database, the statement could be, for example, an INSERT statement or an UPDATE statement. In order to execute such a statement, the DBMS server needs the client device to send the client data to be added to or used to update the database. As noted in the background, the client device typically provides the client data in a text-based format such as, for example, JavaScript Object Notation (JSON) or Extensible Markup Language (XML). As a result, in order to execute the statement and complete the transaction, the DBMS server needs to convert the client data from text format to the format of the record in the database. In this specification, the format of the data stored in the database is referred to as the raw storage format, and the format of a record in a database is referred to herein as the raw record format. The raw storage format and raw record format are typically proprietary for each DBMS system.

Thus, in a traditional DBMS, the DBMS server typically needs to convert the text-based data provided by the client device to the appropriate raw storage format or raw record format of the database. As the number of DBMS transactions gets large, the DBMS server will need to use a greater amount of computing power to process such conversions, thereby potentially degrading DBMS performance. Techniques disclosed herein may alleviate this and other shortcomings associated with a traditional DBMS.

FIG. 1 illustrates various aspects of an exemplary network and system in which the present methods and systems can operate. FIG. 1 shows an example DBMS 100. The DBMS 100 includes a DBMS server 130 and at least one client device 110 communicatively connected to one another over a network 120.

DBMS server 130 includes at least a processor 131, a computer-readable medium 132, and a storage device 133. Storage device 133 stores a database 134. Similarly, client device 110 includes at least a processor 111 and a computer-readable medium 112. DBMS sever 130 and client device 110 can each be implemented as one or more computing devices and each typically includes other hardware as well.

Computer-readable medium 132 of DBMS server 130 stores DBMS software 135 that processor 131 executes from computer-readable medium 132 to manage and maintain database 136. DBMS software 135 is operable to store data in database 136 in a raw storage format.

Computer-readable medium 112 of client device 110 stores at least one application program 113 and at least one DBMS driver 115 that processor 111 executes from computer-readable medium 112 to conduct transactions with database 136. Computer-readable medium 112 of client device 110 also stores at least one in-memory record 114. The In-memory record 114 contains data that client device 110 intends to use in a transaction with at least database 136. Such data in the in-memory record 114, in accordance with the present invention, is stored in the raw storage format of database 136. Essentially, DBMS driver 115 can field requests from application program 113 and interact with DBMS software 135 on DBMS sever 130 to effectuate a transaction with database 136 involving client data stored in the in-memory record 114.

In operation, in accordance with the techniques disclosed herein, application program 113 can generate a request for a transaction with the database 136. The DBMS driver 115 and DBMS software 135 formulate a plan to satisfy the request. In accordance with this plan, the DBMS driver 115 and/or the DBMS software 135 prepare at least one statement that, when executed by the DBMS software 135 in relation to database 136, satisfy the request. Exemplary statements include INSERT and UPDATE, which direct DBMS Software 135 to insert data into database 136, and update data within database 136, respectively. Once the at least one statement is generated, the application program 113 can call an API to provide the client data from the in-memory record 114 to the DBMS server 130. Once received, the DBMS software 135 can execute the statement.

Since the client data is provided to DBMS server 130 in the raw storage format of database 136, the DBMS software 135 does not need to convert the data from one format (for example, a text format) to the raw storage format of database 136. Instead, DBMS software 135 can directly store the client data, as received. This reduces the processing power need to process each transaction with the database 136, thereby increasing the efficiency of DBMS server 130 for each transaction and DBMS 100 as well.

Although DBMS 100 of FIG. 1 shows a client device 110 operable to access a single database 136, the invention is not limited as such. It is contemplated that, in accordance with the present invention, client device 101 can access and engage in transactions with a plurality of databases. In such a case, client device 110 would include application software and DBMS drivers for engaging in transaction with each target database. Further, client device 110 would be operable to create in-memory records for the client data it intends to use in each transaction with each target database, wherein the client data is stored in the in-memory record in the raw storage format of the respective target database.

Similarly, although the DBMS 100 shows a DBMS server 130 for processing transactions with a single client device 110, the invention is not limited as such. It is contemplated that, in accordance with the invention, DBMS server 130 can process transactions with a plurality of client devices. As such, the DBMS software 135 would be operable to respond to requests (e.g., formulate plans, generate statements, expose APIs, receive client data, and execute statements) with each client device.

FIG. 2 shows an example method 200 of DBMS 100. In method 200, at step 201, the application program 113 creates an in-memory record 114 for data it intends to use in a transaction with database 136. At step 202, the application program 113 submits a query to DBMS driver 115 to access the database 136. The query could be, for example, to update a record in the database 136 or to add data within the database 136. At step 203, DBMS driver 115 formulates a plan with the DBMS software 135 to process the transaction. As part of this plan, at step 204, DBMS driver 115 prepares at least one statement to be executed by DBMS software 135. At step 205, application program 113 checks to see if it knows the API for the transaction. If not, at step 206, the API is returned to application program 113 by either the DBMS driver 115 or by the DBMS software 135. At step 207, the application program 113 calls the API to provide the client data from in-memory record 114 to DBMS software 135. At step 208, the DBMS driver 115 passes the client data from the in-memory record 114 to the DBMS server 130 through the API call. Since the client data stored in the in-memory record 114 is in the raw storage format of the database 136, the client data is provided to the DBMS server 130 in the raw storage format of database 136. At step 209, the transaction is processed by DBMS software 135 in accordance with the statement generated by DBMS driver 115, at step 204.

Since the client data is provided by client device 110 to DBMS server 130 in the raw storage format of database 136, DBMS software 135 can execute the statement without having to convert the client data from one format (e.g., text format) to the raw storage format of database 136. Instead, DBMS software 135 can store the received data directly into database 136, as received. This reduces the processing power needed to process each transaction with the database 136, thereby increasing the efficiency of DBMS server 130 for each transaction and DBMS 100 as well.

It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the scope or spirit of the present disclosure. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice disclosed herein.
